PAINT-DISFTRIBUTER.

SPEJIFICATION forming part of Letters Patent No. 292,189, dated January 22, 1884:.

Application filed November 20, 1833. (Model) the manner of connecting the needle-operating arm to the pitman, the manner of supporting the needle-operating arm, the manner of attaching the needle to said arm, the manner of supporting and guiding the bow'-needle, the manner of regulating the stroke of the needle, and the construction of bothneedles, for the attainment of which objects I employ means and construction of parts hereinafter particularly described, and illustrated in the accompanying drawings.

Figure 1 of the drawings is a plan viewof a pigment distributing device with my improvements applied thereto.

Fig. 2 is a side elevation thereof. Fig. 3 is a detail side view of a part of the device, with the air-tube in sec-- tion. Fig. 4 is a detail sectional viewof the air-supply tubes in section, showing the construction of the seat for the valve. Fig. 5 is a side view of the improved eye-needle; Fig. 6, a plan view, showing the construction when both the eye and the bow needlesare used together. Fig. 7 is a plan view of the cover or cap for the wind-wheel and working parts of the machine. Fig. 8 is a detail view of apart of the device, 'showingin section two air-tubes. Fig. 9'is a perspective of the improved bowneedle. Fig. 1.0 is a vertical section through the Wind-wheel, showing the bow-needle.

In said drawings, the letter A indicatesthe hand-piece; B, the pipe for supplying the compressed air to the needles through the branch pipe 0; D, the pivoted arm for controlling the entrance of the air from flexible pipeE to the pipe B;..and F is another branch. pipe for the passage of the air to the wind-wheel. The partsso far described are all of the .old coustru'etion...

To-the side of the hand-piece A there issecured a plate, H, by meansof set-screws a, passing through slots 12 in the plate, so as to permit the plate to be adjusted longitudinally by means of a lever passed downwardly from the top of the hand-piece, and provided with a laterally-projecting Stud, 0, at its lower end, engaging with or fitting into a notch, d, made in the plate. By attaching the adjusting-lever as described, it can be operated by the thumb of the hand which holds the piece A, so as to quickly, easily, and accurately adjust the needle connected to a part of saidplate under the pipe which supplies the air thereto. The plate H has a flange or plate, H, projecting laterally therefrom at right angles thereto, which flange or plate has a post or pin rising from the top, on which the wind-wheel G is slipped, so as to be revolved thereon by the airjet from the pipe F. The top of the wind wheel is provided with a headed pin, 6, which can be shifted from one to another of several holes made in the wheel therefor, so as to change the throw of the pitman J, which is held to the wheel by passing the said pin through an eye at one end of the pitman. By forming the pitman with the eye and the holding-pin with the head, the pitman cannot be shaken from off the holding-pin.

The needle-operating arm K is formed between its ends with an eye, f, into which one end of the pitman will be hooked or linked, so that the two devices will be securely held i together. This arm rests at one end upon a flange, L, extending up from the plate H, the top edge of which flange is inclined downwardly from theend next to the wheel to the end farthest therefrom, at which end it has. a stop-projection, g. The object of providing this flange is to afford a rest for one endof the needle-operating arm, so that the needle may not vibrate in its longitudinal movement, and the top edge is inclined so thatthe inclination of the needle in its movement may be maintainedwithout variance. The opposite end of the needle-arm is bent and fits into the vertical opening in a post, h, rising up from a movable arm, i-in this instance pivoted to a lug, h, projecting from the plate H-so as to allow the needle-arm to swing, and forming one arm of a link, the other arm, 6, of which connects the needle-operating arm with a lever, M. The arm i of the link tits over the post or pin 71, and at the other end is pivoted or riveted to the lever M, which lever is fulcrumed or pivoted to the plate H, as shown in Fig. 1. The plate H also has a catch, j, to engage with the edge of the ordinary cap or cover, N, or a lip thereon, so as to hold said cap down and over the wind-wheel and needleoperating mechanism, to protect the same from injury. The lever M is connected with a spring, 0, of any suitable kind, which in this instance is riveted at one end to the lever, and bears at the other end against the plate H, so that when the lever is pressed to drive forward the needle and then released, the spring will retract the neeedle to its normal position. This spring also permits the needle to be quickly projected forward, so as to expose a greater surface thereof to the air-jet, and as quickly retracted, so as to regulate the quantity of pigment to be deposited.

By connecting the lever to the needlearm by means of the link, as described, the extent of the projection of the needle under the airjet tube can be regulated, and at the same time the length of the needle-stroke lengthened or shortened, for when the lever is pressed so as to project or extend the needle farther u nder the airjettube, the position ofthe postto which the end of the needle-arm is pivoted is changed, so that,as is apparent, the length ofthe stroke will be altered. Thus it will be seen that the length of the stroke can be altered by the movement of the lever, as well as by shifting the connecting-point ofthe pitman to the wind-wheel. The lever M is prevented from slipping or moving upwardly by a rod or pin, 7:, project-- ing across the top of the samei'rom thcplate H.

The needle P, which I will designate as the eyeneedlc, is formed with the eye Zat one end by turning or bending the needle at that end through which the needle-arm passes, so that the two parts are held securely together, although the arm may slide through the eye. The needle tapers from the eye, or from a suitable point between it and the point, so that the amount of pigment to be carried under the air-jet tube may be varied by the graduallyincreasing thickness of the needle, as well as by the throw of the needle. The needle will be very small in diameter, and it of the same diameter from end to end would be apt to sag to a slight extent, or to be quite easily diverted from a straight line; but by gradually increasing its thickness from its point to its eye it will be stiffened, so asto possess that advantage over the other form, as well as the other advantages hereinbefore assigned to it. The needle passes through a slotted guideplate, Q, on the plate H, and through a slot or recess in that portion of the plate H which divides the pigment-receptacle R from the plate supporting the operating mechanism, and then to and under the air-jet tube, its point being under said tube when the parts are standing at rest in their normal position.

A guard, S, pivoted or hinged to the side of plate H, so as to drop over the needle,wi1l hold the latter in place and prevent it from rising up from out of the slot in the plate. The needles may also be held in the slots by theli p or, projecting from the cap or cover.

The pigmentreceptacle is hinged to the hand piece or plate, as usual, and is of the or dinary construction, with the exception of the guide T. This guide-arm may extend from the plate H, as shown in Fig. 1, or from the pigment-receptacle, as shown in Fig. 6, to the airjet tube, or preferably to a pointjust beyond the same, and is provided with a flange at that end, in which is formed a. slot for the backbone of the bow-needle, so as to afford a support and guide for that form of needle when it is desired to use such form, instead of the eye-ncedlein the same device. This bowneedle has its shank a flattened at right angles to its backbone 0, so that when the shank is placed in the slot in the plate H, and in the guide-plate Q, the backbone will set at an angle to the shank, as shown in Figs. 6 and 10. The end of the shank of this needle is slotted, as shown in Fig. 9, so that it may be set down over the needlearm, the lock thus formed holding it to the arm. I prefer to make the shank with the eye-slot, as the needle can then be more readily put in and taken out of place; but it may be made with an eye instead, if desired.

By constructing the bow-needle and supporting it as described, the small wire which carries the pigment is held from contact with any part of the device, so that it is relieved from the frictional contact; that would otherwise exist, and hence it will wear much longer.

If desired, the lug 71 might be made toslide along the plate H, and be held thereto at any desired point by a set-screw, so as to permit of changing the position of the post 71 for the purpose of altering the length of the needlestroke.

It is apparent that many other changes may be made without departing from the spirit of my invention.

Having thus described my invention, what I claim is- 1. The combination of the wind-wheel, the needle-operating arm provided with the eye, the pitman connected to the eye of the operatingarm at one end, and provided at the other end with an eye, and a pin with an. enlarged end for securing the pitman through its eye to the wind-wheel, substantially as set forth.
